Extra Params for GridPanel

[Anburaja]

Hi,
My store :

  
           <Store>
                 <ext:Store ID = "GridSup" runat = "server" >
                  <Reader>
                    <ext:JsonReader IDProperty = "ID">
                     <Fields>
                       <ext:RecordField Name = "item_code" />
                       <ext:RecordField name = "descrip"  />
                       <ext:RecordField name = "Lead" />
                     </Fields>
                    </ext:JsonReader>
                  </Reader>
                </ext:Store>
               </Store>

  
          <Buttons>
              <ext:Button ID="btnSave" runat="server" Icon="Disk" Cls = "grid" Text="Submit" OnClientClick="javascript:return validate();" >
                 <DirectEvents> 
                    <Click OnEvent = "btnSave_Click" > 
                      <ExtraParams>
                        <ext:Parameter Name = "ItemCode"  Value = "#{GridItems}.getRowsValues({selectedOnly: false}).item_code" Mode = "Raw" />
                        <ext:Parameter Name = "Descrip"  Value = "#{GridItems}.getRowsValues({selectedOnly: false}).descrip" Mode = "Raw" />
                        <ext:Parameter Name = "LeadTime"  Value = "#{GridItems}.getRowsValues({selectedOnly: false}).s" Mode = "Raw" />
                      </ExtraParams>
                    </Click>
                 </DirectEvents>
              </ext:Button>
             </Buttons>

The above code shows an error...

How can i use this extra params value in server side
If I am using the below code, gets all the columns value.....

  
          <ext:Parameter Name = "ItemCode"  Value = "#{GridItems}.getRowsValues({selectedOnly: false})" Mode = "Raw" />

In server side,

  
            Dim lsItem As String = e.ExtraParams.Item("ItemCode")
            Dim lsDescrip As String = e.ExtraParams("Descrip")
            Dim lsLeadTime As String = e.ExtraParams("LeadTime")

How to get a particular columns value - I need to get this value in a for loop...


Thanks in advance.....

make sure item_code is a ColumnId in your GridItems - <ext:Column ColumnID="item_code" DataIndex="item_code"></ext:Column>

Haven't tried this, but below might work:

Client-Side
for(i = 0; i < GridItems.store.getCount(); i++)
{
var item_code = GridItems.getRowsValues({ selectedOnly: false })[i].item_code;
}

Are you sure you don't want the selected row on your grid? If so then add a selectionmodel to your griditems:

<SelectionModel>
<ext:RowSelectionModel ID="RowSelectionModel1" runat="server" SingleSelect="true" MoveEditorOnEnter="false">
<DirectEvents>
<RowSelect OnEvent="GridItems_RowSelect" Delay="1" Buffer="250">
<ExtraParams>
<ext:Parameter Name="item_code" Value="record.data.item_code" Mode="Raw" Encode="true" />
</ExtraParams>
</RowSelect>
</DirectEvents>
</ext:RowSelectionModel>
</SelectionModel>

Server-side
Protected Sub GridItems_RowSelect(ByVal sender As Object, ByVal e As DirectEventArgs)
Dim item_code As string = e.ExtraParams("item_code")
End Sub

// Client-side
var gridRowData = Ext.encode(GridItems.getRowsValues({ selectedOnly: true }));
Ext.net.DirectMethods.GridItems_DM(gridRowData);

' Server-side
Imports Newtonsoft.Json
Imports Newtonsoft.Json.Linq

<Ext.Net.DirectMethod()> _
Public Sub GridItems_DM(ByVal gridRowData As String)
Dim itemRec = New With {.item_code = Nothing, .Descrip = Nothing, etc ...}

For Each j As JObject In JSON.Deserialize(gridRowData)
' Deserialize JObject to Anonymous type
Dim _anonObj = JsonConvert.DeserializeAnonymousType(j.ToString, itemRec)

' Now the anonymous type (_anonObj) has the properties of itemRec with the values from the client-side gridpanel
Next
End Sub
